Video phone calls just haven't caught on like all those cinematic depictions of the future said they would--kind of like flying cars. But a bunch of investors led by Bain Capital Ventures still believe. They've pumped a $10 million Series B round into TokBox, a video chat and calling site based in San Francisco. Existing investor Sequoia Capital also participated.

TokBox launched less than a year ago, but it has been working hard, appointing Nick Triantos as CEO, releasing a light desktop application based on Adobe AIR and building code to integrate its video chat into Facebook Chat.

"TokBox has an impressive, and very loyal and energetic user base," Scott Friend, a partner at Bain Capital Ventures who will be joining the start-up's board of directors, said in a statement. "The company is executing well, and its service offers consumers a variety of great features that strongly differentiate TokBox from competitors. We are excited to be investing with our partners at Seqouia in a company we believe has the potential to be the next 'big thing' in Web communication."
